tallhair, thanks for thinking of me but I got out of high temp ceramic coatings a few years ago -- the shipping costs were just too prohibitive for my customers. The cosmetic coatings I concentrate on now are fine for engine parts but will NOT hold up to your exhaust heat.
Whomever you guys ultimately hire, make sure that your motor is well tuned first because some companies' warranty is voided by a dyno test and/or what they determine to be "excessive" heat. Insist that they coat the inside AND the outside (some don't), and ask to see the warranty paperwork -- especially the fine print -- before you commit. For instance, it's a common requirement that you have to use stainless hardware on your exhaust components AND your valve covers above them because rust drips on your new coating job are not covered. There are several colors available nowadays and most are good to about 2200 degrees. If the job's done right and you take decent care of them, they should last for many years. And that's a good thing too with the cost of TTI's and Doug's these days ....
